GREAT! EPIC, simply EPIC!
Few comments though...
1. Is it just me or does the hands and arms seem too small? Perhaps its because the shoulders and elbows are not showing that it created an illusion where the limbs seem not proportionate.
2. The hair in the background starts to look like tentacles.
Maybe its just me, but those are the only flaws I can see. There's no really right and wrong in art, and I'm no art critic. Its awesome and nothing much can make this artwork more epic. Good day, to you, sirs.
